• Expansion of 1/((1-2x)(1-5x)(1-6x)(1-12x)).at n=4A025991
• Number of (k+1)-tuples of integers modulo n (x_1,...,x_k,s) such that at least one subset of the x_i sums to s mod n. In other words, n^k times the expected number of distinct subset sums mod n of k integers mod n chosen uniformly at random. Read by antidiagonals, i.e., with entries in the order (n,k)=(1,1),(1,2),(2,1),(1,3),(2,2),(3,1),...at n=49A098966
• Number of permutations of length n which avoid the patterns 1243, 4132, 4321.at n=13A116771
• Prime numbersat n=7602
